menses.

Application filed March 13 To all whom it may concern Be it known thatI, ALFRED Gr. Lneon, a citizen of the United States, residing atBrockton, county of Plymouth, State of Massachusetts, have invented acertain new and useful Improvement in Shoe-Forms, of which the followingis a specification, reference being had therein to the accompanyingdrawings.

My invention has for its object a new and improved adjusting device bymeans of which the opposing sides of a leatherboard shoe-form may beexpanded after the shoeform has been inserted in the shoe for thepurpose of causing the shoe-form to fitsnugly into the shoe and also toadjust the shoeform for use in shoes of different sizes. Heretofore ithas been customary to employ for this purpose a simple toggle joint,composed of two members pivoted to each other at the center and to thesides of the shoeform at their ends.

Shoe-forms provided with the ordinary toggle joint can be expanded onlya predetermined amount. which is limited by the throw of the togglejoint, and they must be expanded to this extent whenever in place, asotherwise the elasticity of the shoe will cause the toggle joint toresume its bent position.

My present invention provides a toggle joint which can be adjusted fordifferent widths of shoes and which is less likely to be bent by theelasticity of the shoe.

The invention will be fully understood by reference to the followingspecification, taken in connection with the accompanying drawings, andthe novel features thereof are pointed out and clearly defined in theclaims at the close of this specification.

In the drawings, Figure 1 is a bottom view of a shoe form to which myimproved toggle joint is applied. the toggle joint being shown in theposition occupied by 1t when the shoe form is expanded. Fig. 2 shows thetoggle joint with the members in bent position and the latch disengaged.Fig. 3 shows the toggle joint in bent position but with the latchengaging the pivot. Fig. 4 is a plan view of the toggle joint.

Referring now to the drawings, at A and B respectively, see Fig. 1, areshown the opposing inturned sides of the bottom of the shoe-form. Thetoggle joint consists of two toggle members 11 and 12 pivoted at 13 and14 to the inturned sides A and B of the shoe Specification of Letterslatent.

form. The member 11 is preferably pro vided with a thumb piece 16 andthe member 12 is slotted, as shown at 17, toreceive a pivot stud 15carried by the member 11 and which pivot-stud may be moved toward andaway from the side B of the shoe form. The stud 15 serves as the centralpivot of the toggle when the latter is being broken or straightened out.coincidentally with the pivot of the toggle member 12, is secured alatch18 having notches 19 in one edge thereof, said notches being of a sizeadapted to receive the said pivot stud 15. The latch is also preferablyprovided with a thumb piece 20. In the form shown in the drawings, thelatch is in- To the pivot stud 14,

terposed between the two toggle members 11 and 12, and is secured to thepivot 14.

If the shoe form is to be inserted in a relatively wide shoe, the togglejoint is put in the position shown in Fig. 2 and the latch 18 is swungaround the pivot 14 until adjustment for different widths ofshoes,

the width of the shoe determining the notch to be employed. Asordinarily constructed, the form will be of the width of the shoe forwhich it was constructed when the pivot stud is in the middle notch, andwill be correctly adjusted for a shoe one size wider when it is in oneend notch and for a-shoe one size narrower when it is in the other endnotch. More notches may be provided if desired. The thumb piece 20affords a convenient means of engaging and disengaging the latch. andthe latch 18 being interposed between the two toggle members 11 and 12tends to wedge the toggle members apart and to prevent the toggle jointbeing displaced by pressure on the sides of the shoe form.

Wh t I claim is:

1. The combination with a shoe form pro vided at its bottom withopposite inturned sides, of a toggle comprising two members each ofwhich is pivoted to one of said inturned sides, one of said membersbeing provided with a slot and the other with a stud adiustable in saidslot and serving as the central pivot of the toggle, and alatch pivotedto one of said inturned sides coincis dently with one of said togglemembers and provided with a plurality of notches either of which may beengaged with said stud to hold the toggle in any desired. position ofadjustment.

The combination with a shoe form provided at its bottom with oppositeinturned sides, of a toggle comprising two members each of which ispivoted to one of said inturned sides, one of said members beingprovided with a slot and the other with a stud adjustable in said slotand serving as the central pivot of the toggle, and a latch pivoted toone 01 said inturned sides coincidently with one of said toggle membersand provided with a plurality of notches either of which may be engagedwith said stud to hold the toggle in any desired position of adjustment,said latch being so arranged as to be interposed between said togglemembers when the toggle is closed.

3. The combination with a shoe form provided at its bottom with oppositeinturned sides, of a toggle comprising two members each of which ispivoted to one of said inturned sides, one of said members beingprovided with a slot and the other with a stud adjustable in said slotand serving as the central pivot of the toggle, and a latch pivoted toone of said inturned sides coincidently with one of said toggle membersand provided with a plurality of notches either or" which may be engagedwith said stud to hold the toggle in any desired position of adjustment,said latch and one of said toggle members being each provided with anoperating thumb-piece.

In testimony whereof I afiixv my signature, in presence of twowitnesses.
